RE: Semi OT: Anybody using the EIGRP protocal?
by Thomas Salmen 01 Mar '02

01 Mar '02

Enabling eigrp is the same as with most other routing protocols: router eigrp 10 network 10.1.0.0 network 192.168.5.0 network x.x.x.x We don't use EIGRP ourselves, and I don't have a huge amount of experience with it personally (other than lab study). I'm not aware of anyone using it (not that this means anything - as far as I know everyone in the country could be). EIGRP is often referred to as a balanced-hybrid routing protocol, in that it displays properties of both distance vector and link state protocols. Unlike distance-vector (eg RIP), EIGRP does not indiscriminately fire routing updates across the 'net; unlike link-state protocols, EIGRP treats everything as one large area. Because of this, EIGRP can become more troublesome to manage in larger internetworks: care must be taken to design a network which does not destabilise easily. OSPF does a nice job of reducing this complexity by making it intuitive to break a network into individual areas, and (essentially) routing between them; the process with EIGRP is rather more manual. Routing information can be summarised at router interfaces, creating a similarly hierarchical topology. Good initial network design can eliminate many problems from the beginning. PS - like I said, I don't have a lot of experience with EIGRP first-hand - most of what I say here is inferred through study or research. Regarding your last question: if you only have the one connection to the outside world (eg your hypothetical frame), you don't need to run any routing protocol over it. Your router (the 2500) only needs a default router pointing to the appropriate next hop - how the next hop decides how to forward packets you send it is irrelevant, as far as you are concerned. You can be using RIP, your provider could use OSPF. Just as long as they get where they are supposed to. Of course, the situation becomes far more interesting with two upstream pipes... -- Regards, Thomas Salmen Network Manager Radionet Ltd. 72 Paul Matthews Road Albany, Auckland, New Zealand Ph: +64 9 4140 300 -----Original Message----- From: Malcolm Lockyer [mailto:hivemindhivemind(a)hotmail.com] Sent: Saturday, 2 March 2002 7:47 p.m. To: nznog(a)list.waikato.ac.nz Subject: Semi OT: Anybody using the EIGRP protocal? Hello all.. I was messing 'round on amazon (reading all the book exerpts :P) and in a cisco book I found some stuff about EIGRP routing protocal. What I read about it, it sounded really good, like had all the benifits of OSPF and uses less CPU power, and easier to setup etc. So, I was just curious, is anybody in NZ using EIGRP? Oh, and I'm a stupid newbie, so I'm sorry if the next few questions are kind silly, but, I guess everybody has gotta start somewhere.. :P I've only worked with cisco 2500's, so this may be totally off for the newer routers, but... When configuring the 2503 and 2514 with IOS 12.0, it seems that the only protocals it, "likes" is RIP and IGRP, say if I wanted to use EIGRP is it just a matter of saying somthing like "ip EIGRP" on the interfaces, or do you have to do somthing like upgrade to an IOS with EIGRP included? Also I was wondering, say I had a mid sized network, and I decided that I wanted to use, EIGRP protocal on my network. But, say, I was getting internet delivered over frame relay, and that service provider was using, say RIP. Would that work? Or do you need to do somthing special to the routers to allow somthing like that, data moving between routing protocals??

Porirua Jetstream
by Steve Winter 01 Mar '02

01 Mar '02

Hi, I'm a 'sometimes' end user of Jetstream, who has been 'enjoying' the recent thread... Now I say sometimes because I have been unable to connect for the last approx. 20 hours...my ISP, who shall at this time remain nameless, has recently informed me that this is a Telecom problem within the entire Porirua basin... As the same 'tech' person is the one who assured me that to reboot an external router I had to restart my computer, and also asked me to tell him what results I got from a tracert to their server were, when I had just spent 5 min explaining that I had no internet connection, in all honesty I have little faith in the accuracy of this statement... :-) A web search turns up nothing useful...just wondered if anyone on the list can confirm or deny... Kind regards Steve - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Just a note that we will be doing some work on our link to APE at 3pm this afternoon. Hopefully it should only take a minutes but be might see the odd error. We have also been adjusting our wellington setup this afternoon if people notice any changes to our WIX advertising. This should all be stable soon. -- Simon Lyall. | Newsmaster | Work: simon.lyall(a)ihug.co.nz Senior Network/System Admin | Postmaster | Home: simon(a)darkmere.gen.nz ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Juniper Networks(r) Routers: The Complete Reference
by Dean Pemberton 28 Feb '02

28 Feb '02

I knew keeping quiet about Rogers 10GigE vendor spam was going to pay off eventually. This is not so much vendor spam as a Public Service announcement. =) The first Juniper Networks Reference book has just been released. It was written by some of our best engineers (read as: HEAPS better than me), and it aims to be as the title says "The Complete Reference". One of the Authors is Jeff Doyle. You might remember him from such small books as "Routing TCP/IP Volume 1 and 2". So either keep a lookout at your local bookstore, make an order, or here is the amazon URL. http://www.amazon.com/exec/obidos/ASIN/0072194812/qid=1014934141/sr=8-1/ref… - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

I've got a goodly number of identical switches in Wellington all running the same code release, so I've no reason to believe the 3524's in the Sky tower will display altitude sickness. I've also discovered that if you delete all the HTML off the flash, you can fit two images on (the old and the new), which does give us a way back if they display Auckland specific silliness. In addition, we'll have a tech on standby - he needs to be on site to install gigabit between the switches (part of the reason for the upgrade is to install an IOS release that supports copper GBICs). So if I do royally putz something up (fairly unlikely, given that I've done about 60 of these upgrades in the last two months), we'll have somebody there to type stuff into the boot loader and reinstantiate the old image.

Outage on APE this evening
by Simon Blake 27 Feb '02

27 Feb '02

Hi Folks. A quick heads up, there will be an outage of approximately 75 seconds on each of the APE switches tomorrow (Fri Mar 1) morning at 6am (timing is negotiable, if anybody has a good reason to have it earlier or later). This is to upgrade IOS on each box (to the same level as the same switches in Wgtn).
